[Sugar-devel] Network version of Abecedarium: why and how

[lionel at olpc-france.org]

Hi all,

 

I’ve released last week my Abecedarium activity for Sugar 0.96+. One issue
with this activity is that, due to number of contents (1500 images and
sounds), its size is about 100Mo.

 

We want to deploy the activity on our Nosy Komba deployment this year: 150
XO-1 and 50 XO-1.5.

Because we’ve got other activities to deploy, we compute:

-          The free space on a XO-1 and XO-1.5 with Sugar 0.96 without any
activity: 550 Mo for XO-1, 2645Mo for XO-1.5.

-          The size of all activities that we planned to install, see the
spreadsheet [1].

Unfortunately 100 Mo is too big for the XO-1 with some other big activities
(GCompris, Tuxmath, TurtleArt, Speak, 
).

 

So I choose to develop a new version named “Abecedarium Net” [2] without any
content included, so with a size of only 6Mo.

The idea is to deploy all contents on a school/web server instead of into
the activity. A config file in the activity has to be set with the URL of
the content, or it could be set from a dialog popup. The activity test the
network regularly and display the status.

Because Abecedarium is wrote in HTML5, deploying the web server just mean to
copy the content of the full activity on the server.

I’ve explained the full process in the activity description.

I will test it myself on our School Server at Madagascar but do not hesitate
in the meantime to test it and give me feedback.

 

Best regards from France.

 

                Lionel.
